Other treaty arrangements with the EU include 'EEA' (European Economic Area') and 'EFTA' (European Free Trade Area). I have a little knowledge of what these other treaty arrangements cover, and some of the bits I do know, I don't like - I dislike them enough that they are no more acceptable than full EU membership.
...provides for the free movement of persons... adopting almost all the relevant EU legislation other than laws regarding agriculture and fisheries.
Except for Switzerland, the EFTA members are also members of the European Economic Area (EEA)Further Switserland (the only non EEA member) is also part the EU single market (meaning EU rules apply to all products/services even if produced and sold internally) and a signatory of the Schengen Agreement allowing undocumented movement of people between members (http://en.wikipedia.org/wiki/Schengen_Agreement)
My Red-Lines include:-
1) UK Border Control
No entry to the UK for foreign nationals unless they have first been given specific permission. And certainly no entry for work or settlement without further qualification.
2) Domestic production/trade to be regulated only by UK domestic law, with no input from external, foreign authorities.
The UK will decide or itself it is wants to limit the power of vaccum cleaners, or sell products in metric or imperial measures etc.
Neither EFTA nor EEA pass either of these tests, so neither is an acceptable alternate should we leave the EU.
